Great deal

diy router copy machine. excellent base to start with.

These are the Y axis rails for a 48 X 96 inch CNC Mill I'm building. I bought 4 rails took two rails, removed them from the base shifted the base by two holes and remounted it then I have two sets of 8 foot rails. and the bearings slide right across the TINY gap as if it were not there

I bought these rails to fabricate a custom TV mount for a VERY large flatscreen we bought. I wanted to be able to slide the tv to the side to be able to access a hidden area behind the tv where the receiver, etc would be stored. The tv weighs in at 97 lbs, and I am able to slide it back and forth on these with a light touch of only 1 finger. They seem to be well constructed and are well worth the price.

worth getting more at the price I paid.

Very pleased with these rails, recieved them fast. These rails are good built with high quality parts. Rails roll nicely and seem to support a good amount of weight. I had some questions for the seller and they were prompt and very helpfull.

A great buy for the money. Rails are nice with just a few surface scratches. Bearings are not perfect and each one has a different feel to it. I cleaned an oiled them and a lot of metal shavings were in there. Definately clean these.Packaging was great and fast shipping.

Bearings are a bit rough. Rail is straight and true until the end screws securing it to the rail. The rail bends up a little on both ends. Side to side is good.

Super I wanted this items long ago for a projectSomething like a sliding table and they are perfectfor my table I’ll will recommend this items to any home hobbyist. they are perfect for projects with a retractable or sliding mechanism.

I would not use these on a CNC machine, but for making tight tolerance slides for other applications, they are just fine.The linear motion bearings can be a bit rough when they roll, catching at points and rolling fine at others, like the balls have flat spots, but can’t visually see anything wrong with them.
